I am sorry to bother you further but I dont know exactly how to do
the stack function. I mean I start with the excel file and I convert it into a txt file,
then when e where do I write the script as reported in gretl's guide?
Allin just now mentioned the gretl console (Tools/gretl console) and the
built-in script editor (File/Script files/New script/gretl script).
Another workaround might be to use Google Spreadsheets, apparently it
has some handy tools to manipulate ranges like this and stack them.
(Search for "data ranges".)
cheers
